Multi-unit abutment

Abutment used with dental implants

A multi-unit abutment (MUA) is an abutment most commonly used with dental implants in "All-on-Four" protocols. They are designed for screw-retained group restorations, which are often used in combination with angled dental implants and whole arch replacements, as well as screw fixation of bridges made of zirconium or metal-ceramic group restorations to the implant.
